BRIEF DESCRIPTION OF THE DRAWINGS

The following detailed description, given by way of example and not intended to limit the present invention solely thereto, will best be appreciated in conjunction with the accompanying drawings, wherein like reference numerals denote like elements and parts, in which:

FIG. 1 is a schematic illustration of the body pillow in accordance with the present invention; and

FIG. 2 is a schematic illustration of a body pillow in accordance with another embodiment of the present invention.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

The body pillow of the present invention is comprised of three separate chambers, each with filling material therein. Referring now to the drawings, and particularly to FIG. 1 thereof, body pillow 10 of the present invention includes a housing 12 that is comprised of three separate chambers 20, 22 and 24. The chambers are internally separated from one another by two baffles 14 and 16. In particular, the first baffle 14 separates first chamber 20 from second chamber 22, and the second baffle 16 separates second chamber 22 from third chamber 24. Body pillow 10 also includes ends 26 and 28, as shown.

Each of the three chambers 20, 22 and 24 is filled with suitable filling material 18. Filling material 18 may be cotton, polyester, feathers, down, a combination of feathers and down, or other known filling material. Filling material 18 may also be the filling material described in U.S. Pat. No. 7,074,242, generally referred to as Lyocell Down. U.S. Pat. No. 7,074,242 is owned by the assignee of the present invention and is incorporated herein by reference. Each of the chambers may be filled with the same filling material to provide the same, or nearly the same, firmness levels as well as other characteristics (e.g., amount of “memory”). The chambers also may have different densities of the same filling material to provide chambers with different characteristics, such as firmness levels and/or thicknesses. Alternatively, the chambers may be filled with different filling materials. For example, each of the three chambers may be filled with different filling materials thus provide pillow segments with different characteristics. As another example, chambers 20 and 24 are filled with the same filling material, and middle chamber 22 is filled with a different filling material thus providing a pillow mid-section that has one or more different characteristics than the outer ends of the pillow.

Each chamber 20, 22 and 24 preferably is filled with filling material 18 via a respective chamber access opening 30, 32 and 34. Each opening preferably includes a suitable mechanism for preventing filling material 18 from leaving the respective chamber, such as by use of a zipper connection, a Velcro connection or other known, appropriate device. The size and location of each opening 30, 32 and 34 may differ from that shown in the figures.

Body pillow 10 of the present invention may be manufactured from any suitable material, such as cotton, although other materials may be utilized. Body pillow 10 may have the dimensions of, for example, 60 inches by 20 inches by 6 inches, thus providing an oval cross-section. The body pillow of the present invention may have different dimensions and/or shape, including a round cross-section. Preferably, although not necessarily, chambers 20, 22 and 24 have the same dimensions (e.g., 20 inches by 20 inches by 6 inches) and generally the same shape. In a variation, the chambers have different dimensions and/or shapes. As an example, chamber 22 (i.e., the central chamber) has a length substantially longer than the two outer chambers 20 and 24.

In accordance with the present invention, baffles 14 and 16 of body pillow 10 prevent filling material 18 within each of the chambers from shifting to the other chambers. Thus, normal use of the body pillow of the present does not cause filling material to shift. The construction of the body pillow of the present invention as described herein also prevents shifting of filling material during washing, including washing of the body pillow in residential or commercial washing machines. The construction of the body pillow of the present invention further advantageously provides for a product with a consistent density along its top, middle and bottom sections. Still further, the multi-compartment/multi-baffle construction of the body pillow of the present invention provides for better washability, due to the lack of shifting of filling material between the body pillow's sections.

Body pillow 10 of the present invention and as shown in FIG. 1 includes multiple, internal compartments, while providing an exterior appearance of a single pillow. However, the present invention includes body pillows that have an external appearance that visibly show each of the multiple compartments. In particular, FIG. 2 of the drawings is a schematic diagram of body pillow 50 in accordance with another embodiment of the present invention. As shown in FIG. 2, each of the three chambers 60, 62 and 64 has a shape in which the respective inner edges (e.g., 70, 72 and 74) curve inward, so that the multiple compartment construction is visible. As shown in the exemplary design presented in FIG. 2, body pillow 50 externally has the appearance of three relatively smaller, distinct pillows disposed in a side-by-side and contacting arrangement.

The construction of body pillow 50 has an exterior appearance of three pillows that are adjacent and in contact with one another. The first embodiment shown in FIG. 1 may also, in a variation thereof, have an exterior appearance of three distinct pillows disposed adjacent to and in contact with one another. In either case, the body pillow of the present invention may be used in the ordinary manner, that is, to support a person's arms, body and/or legs, and further may be placed (generally when not in use by a person) at the head of a bed (or other location and/or on another piece of furniture, e.g., a sofa). Thus, when not in use, various designs of the body pillow of the present invention operate as a functionally decorative element.

The present invention has been described above and shown in the drawings. The body pillow of the present invention may have different configurations. For example, the body pillow may have a different number of multiple compartments than that shown in the drawings (e.g., four compartments, five compartments, etc.). The body pillow may have various different shapes and/or sizes. For example, the body pillow may have a cross-section that is round, as already mentioned, or another different shaped cross-section. The body pillow may have different lengths, widths, depths, etc. Moreover, the present invention has been described with reference to drawings that show multiple compartments that are disposed along a single axis (i.e., a straight line) that extends along a length of the pillow. The present invention, however, is not limited to this construction and includes body pillows that include compartments that do not extend along a straight line. For example, the compartments may extended a long a curved line, so as to provide a sort-of curved body pillow with multiple compartments disposed within in. Hence, while the present invention has been described in the context of a number of embodiments and variations, it is to be understood that other expedients known to those skilled in the art may be employed without departing from the spirit of the invention.
